Dispersal of released infected adults and subsequent spread of a Wolbachia infection through a landscape is possible. Results are similar to those from single-node studies, but it seems it is even more important to release infected adults when both the release node and surrounding areas have low abundances. This not only increases the fixation in the introduced plot independently, but also reduces immigration from surrounding plots.
Using unstructured models can lead to greatly overestimating infection frequencies, but also to different dynamics than in agestructured models. The use of unstructured models should therefore be avoided. This is especially true if using models with multiple nodes.
